HAROLD TILLIAM SANDERSON, OF LONDON, ENGLAND.

PRINTING WALL-PAPER.

SPECIFICATION forming part of Letters Patent No. 569,237, dated October 13, 1896.

Application filed August 20,1894. Serial No. 520,835. (No model.) Patented in England May 80, 1894:, No. 10,529, and in France July 30, 1894,11'0. 240,394.

.'0 (LZZ whom it may concrn:

Be it known that I, HARoLD WILLIAM SAN- .DERSON, manufacturer of paper-hangings, a subject of the Queen of Great Britain and Ireland, and a resident of Ohiswick, London, England, have invented certain new and useful Improvements in and Relating to the Printing of fall-Papers, applicable also to the printing of posters, textile fabrics, and the like, (for which I have obtained a patent in Great Britain, No. 10,529, dated May 30, 189-, and in France, N o. OQ, dated July 30, 18%,) of which the following is a specification, reference being had to the accompanying drawing, which represents in side elevation and partly in section the arrangement of the different parts.

In carrying my invention into practice I construct a pair of opposite side frames of any suitable material and having any desired shape or form, which side frames are adapted by means of bearings to carry a shaft A, upon which a suitably constructed drum B is mounted. At a suitable part of said side frames I provide a pair of opposite sliding bearings O, the arrangement of the slides being such that the said bearings C maybe adjusted in any desired direction relative to the drum B. Said bearings C serve to supporta spindle E, Aupon which a printing-roller F is mounted, which printing-roller is formed or provided on its periphery with any desired design engraved so as to leave the design in relief, or any required design may be reproduced from the wood engraving by stereotype, electrotype, or other well-known method and mounted on the printing-roller, or any suitable design may be produced by any wellhnown process, such as zincograph and photo process, and mounted on the printing-roller. In convenient proximity to the said printingroller F, I provide a duet or fountain G, which is adjusted with a suitable ink-roller I-I, adapted to be revolved as hereinafter described, and vibrator K. Said duet or fountain G is adapted to receive the printing-mk or the lithographic ink sufficiently thinned down, and for the purpose of regulating the supply of such ink to the ink-roller H said duct is constructed so that a knife or the like L may, by means of set-screws M, be set farther from or closer to the said ink-roller H, so as to allow a greater or less quantity of such ink to be carried on said revolving inkroller. Said roller I'I receives its rotating motion from the pitch-wheel or other suitable source by means of suitable gearing in the usual manner, and for the purpose of imparting vibratory 'movement to the vibrator. K, I form or provide one of the gear-Wheels referred to with an arm N, by means of which the rearwardly-extending end O of the rocking frame P is depressed and consequently the opposite end of said rocking frame, which carries the vibrator K, is raised until the said Vibrator K comes in contact with the inktransmitting roller Q, so that comparatively only a small quantity of ink is transferred from the duet G to the roller Q.

For the purpose of obtaining an even distribution of the ink on the roller Q, I provide two or more ink-distributing rollers Q', and I prefer also to cause the roller Q to vibrate in the direction of its length, and for the purpose of inking the printing-roller F, I provide two or more inking-rollers R, which are in contact both with the ink-transmitting roller Q and the printing-roller F, as shown, and in order to further insure an even distribution of the ink onto the printing-roller F, I prefer to provide one or more additional inking-rollers R', which receive their ink from the inking-rollers R by means of one or more intermediate rollers R2.

The diameter of the printing-roller F depends upon the length of the pattern or design being printed, and in order that within reasonable limits a printing-roller of any desired diameter may be used I provide the sliding or adj ustable bearings O, as hereinbefore described. The rollers Q Q' R R' R2 are also supported in adj usta-ble bearings, so that they may be adjusted and set to suit a printing-roller of larger or smaller diameter.

The drum B serves to support the paper or textile fabric S while being printed, and in order that the pressure of the printing-roller F against the paper or teXtile fabric shall not injure the latter, and also so that all the fine lines may be more readily printed, I dispense with the usual eomparatively thick blanket or felt, which is wound around the IOO drum, and fix to said drum any suitable thin material, or if found requisite snoh thin material may be dispensed With, so that the surface thereof will be eomparatively hard, in place of the soft surface hitherto employed in the printing' of Wall-papers by means of raised rollers, thus making the drums larger in eomparison With drums hitherto used.

Having now described my invention, what I elam as new, and desire to secure by Letters Patent, is-

1. In a Wallpaper-printing' machine the combination of a duet G provided with a knife L and screws M, ink-roller H adapted to receive rotary motion, ink-carryng rollers Q, ink-distributing rollers Q', inking-rollers R, R', intermediate roller R2, printing-roller F and vibrator K carried by a roekin` frame P adapted to be vibrated by means of an arm N on the gearing, all for the purposes and substantally as set forth. p

2. In a wall-paper-printingmaohinehaving an ink-roller H which is adapted to receive rotary motion, ink-earrying' rollers Q, inkdistributing rollers Q', inking-rollers R, R', intermediate rollers R2 and printing-rollers F, the combination therewith of a duet G having a knife L and set-serews M by means of which set-sorews and knife the quantity of ink supplied onto the ink-roller I-I may be regulated, and a vibrator K carried by a rooking' frame P adapted to have rooking motion imparted to it by means of suitably-supported arms N Whieh are adapted to depress the rear end O of said rooking frame and thereby raise the opposite and Vibrator-oarrying end so that said vibrator is made to intermittently come in contact With the ink-transmitting roller G, all for the purposes and substantially as set forth.

In wtness whereof I have hereunto set my o hand in presence of two witnesses.

HAROLD WILLIAM SANDERSON. Titnessesz ALEXANDER E. VJILLIAMS, RICHARD WILLARD.
